Make the install-llvm-libraries-stripped and install-clang-libraries-stripped
targets depend on the individual library stripped install targets, so
that they actually install the libraries.
Summary:
Related to D75672, this patch adds EVT::isFixedLengthVector to determine
if the underlying vector type is of fixed length.
An assert is introduced in EVT::getVectorNumElements that triggers for
types that aren't fixed length. This is currently guarded by a flag
added D75297 that is off by default and has been renamed to the more
generic ENABLE_STRICT_FIXED_SIZE_VECTORS.
Ideally we want to get rid of getVectorNumElements but a quick grep
shows there are >350 uses in lib/CodeGen and 75 in lib/Target/AArch64
alone. All of these probably aren't EVT::getVectorNumElements (some may
be the MVT equivalent), but there are many places to fixup and having
the assert on by default would make the SVE upstreaming effort
difficult.

This patch removes compiler runtime assertions that ensure the implicit
conversion are only guaranteed to work for fixed-width vectors.
With the assert it would be impossible to get _anything_ to build until
the
entire codebase has been upgraded, even when the indiscriminate uses of
the size as uint64_t would work fine for both scalable and fixed-width
types.
This issue will need to be addressed differently, with build-time errors
rather than assertion failures, but that effort falls beyond the scope
of this patch.
Returning the scalable size and avoiding the assert in getFixedSize()
is a temporary stop-gap in order to use LLVM for compiling and using
the SVE ACLE intrinsics.

Summary:
This patch makes the AVR backend an official target of LLVM, serving
as a request for comments for moving the AVR backend out of
experimental.
A future patch will move the LLVM AVR buildbot (llvm-avr-linux) from the
staging buildmaster to the production buildmaster, so error emails will
start to go out.
Summary of the backend
----------------------
- 16-bit little endian
- AsmParser based assembly parser
- uses the MC library for generating AVR ELFs
- most logic driven from standard TableGen-erated tables like other
backends
- passes all of the test suite under `check-all`, including generic
CodeGen and DebugInfo tests
- Used in two frontends
- Limited, but functional support for DebugInfo and LLVM DWARF dumping
- Binary compatible with AVR-GCC and avr-{libc,libgcc} for the most part
- Cannot lower 32-bit shifts due to a bug, can lower shifts larger or
smaller
- Supports assembly/MC for all the entire AVR ISA, generally generates poorly
optimized machine instructions, with most focus thus far on correctness
I've added reviewers and subscribers from previous patches where backends were made official,
and those who participated in the recent thread on llvm-dev, please add anybody I've missed.

1079c68a "Attempt to fix ZLIB CMake logic on Windows"
This changed the output of llvm-config --system-libs, and more
importantly it broke stand-alone builds. Instead of piling on more fix
attempts, let's revert this to reduce the risk of more breakages.
Summary:
AIX supports both 32-bit and 64-bit environments (with 32-bit being the default). This patch improves support for building LLVM on AIX in both 32-bit and 64-bit mode.
- Change host detection to return correct 32/64-bit triple as config_guess does not return the correct version on 64-bit. This can confuse JIT tests and other things that care about what the host triple is.
- Remove manual setting of 64-bit flags on AIX. AIX provides OBJECT_MODE environment variable to enable the user to obtain a 64-bit development environment. CMake will properly set these flags provided the user sets the correct OBJECT_MODE before configuring and setting them manually will interfere with 32-bit builds.
- Don't present the LLVM_BUILD_32_BITS option on AIX, users should use OBJECT_MODE when running CMake instead.

zlib usage on Windows has caused issues in the past. Furthermore, the
GNUWin32 library can be detected and used although the headers are not
available. Require Windows to explicitly opt in.
Rather than handling zlib handling manually, use `find_package` from CMake
to find zlib properly. Use this to normalize the `LLVM_ENABLE_ZLIB`,
`HAVE_ZLIB`, `HAVE_ZLIB_H`. Furthermore, require zlib if `LLVM_ENABLE_ZLIB` is
set to `YES`, which requires the distributor to explicitly select whether
zlib is enabled or not. This simplifies the CMake handling and usage in
the rest of the tooling.
This restores 68a235d07f9e7049c7eb0c8091f37e385327ac28,
e6c7ed6d2164a0659fd9f6ee44f1375d301e3cad. The problem with the windows
bot is a need for clearing the cache.
This reverts commit e6c7ed6d2164a0659fd9f6ee44f1375d301e3cad.
This commit was an attempt to fix the build bots, but it still left the
clang-x64-windows-msvc bot in a broken state.
There's quite a lot of references to Polly in the LLVM CMake codebase. However
the registration pattern used by Polly could be useful to other external
projects: thanks to that mechanism it would be possible to develop LLVM
extension without touching the LLVM code base.
This patch has two effects:
1. Remove all code specific to Polly in the llvm/clang codebase, replaicing it
with a generic mechanism
2. Provide a generic mechanism to register compiler extensions.
A compiler extension is similar to a pass plugin, with the notable difference
that the compiler extension can be configured to be built dynamically (like
plugins) or statically (like regular passes).
As a result, people willing to add extra passes to clang/opt can do it using a
separate code repo, but still have their pass be linked in clang/opt as built-in
passes.

Treat the flag `LLVM_ENABLE_ZLIB` as a tri-bool, `FORCE_ON` being `ON`,

It is sometimes useful to have the C++ standard library linked into the
assembly when compiling clang, particularly when distributing a compiler
onto systems that don't have a copy of stdlibc++ or libc++ installed.
This functionality should work with either GCC or Clang as the host
compiler, though statically linking libc++ (as may be required for
licensing purposes) is only possible if the host compiler is Clang with
a copy of libc++ available.
